Recording/reproduction device and method for digital broadcasting

摘要

A recording/reproduction device is provided wherein service content having interactivity can be restored even when recorded. In recording mode, a transport stream from a receiving device (34) is received and a conversion device (36) converts this to a packet-multiplexed stream in a condition suitable for recording, which is then output as a converted stream. The conversion device (36) selects packets relating to a desired service from the transport stream and, of these packets, selects only packets needed for reproduction and uses these to generate a converted stream. A recording device (38) records this converted stream on a recording medium (44). In reproduction mode, the converted stream from recording medium (44) is read by means of a reading device (42) and supplied to a restoration device (40). Restoration device (40), in accordance with the content of this converted stream, restores and outputs a service content signal (for example a composite signal such as NTSC). A video/image output device (46) receives this service content signal and outputs video/images.
